Years: 1996 Location: Chicago Mainstage Where you've seen her: As the feisty Liz Lemon on "30 Rock," the sitcom she created. Her name was everywhere during the 2008 election when she returned to "SNL"---where she once served as the head writer---to show off her Sarah Palin impression. She's made it to the big screen with "Mean Girls," which she wrote, and "Baby Mama."
